What are some sketch comedy shows (https://en.wikipedia.org/wiki/Category:Television_sketch_shows) that seem to have been lost to time?

The Dana Carvey Show, which I loved.

The Ben Stiller Show.

Kids in the Hall, which no one ever talks about anymore but was so popular.

Bizarre, which starred John Byner/Super Dave Osbourne (RIP) and which was sort of like a cheesy Canadian Benny Hill-type show.
